Nah…I’m calling it. It’s the fire-lighting monk and The Immortal, cause Jin really is part of The Immortal (which is what Bunny suspected) and once he got hurt, he changed back to his true self. Yeah…that’s it…totally…I guess…maybe…ok, I’m probably way off.

Of course Jin could be the sort of immortal that isn’t impervious to harm/pain, so he could look like he should be dead/impaled through the chest but then brush it off like he was the black knight, if the black knight actually felt pain…. (Can’t die, but can still be injured to no end)
